T0 at whom it mea soy went- Be it known that A l a subject of the lihnperor of i Elsi/T15. and a resident of Montcleir, county oi anti State oi New Jersey, have invented tain new and. useful Ilmprovenie. "cs l n several groups which exterior corners will e cylinder closely fitting o'rical insulating-tubes t t l or oil ducts in the rei all the corners. The

A further object oi the infventh I to t vicle fol such variations in size as tenipei'i. JZG changes through electi other causes.

In the ecconipzm ing sheet of drew' which forms 2), par oi this application, i ure 1 is a side elex m. of co'ree trellisformer embodying my ion, in which the coils on one leg of the tra for and one end of ol the ole the coils are broken away. 51g.
